Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.

TIMKEN tapered roller bearings
TIMKEN tapered roller bearings, as everyone knows, TIMKEN Bearing Company is the world's largest manufacturer of tapered roller bearings. So what is the specific TIMKEN tapered roller bearings do? Specific TIMKEN tapered roller bearings have those features do? TIMKEN distributor in China will take you into What is the tapered roller bearings
Tapered roller bearings mainly bear radial diameter and axial joint load. These bearings are separable bearings, the inner ring with roller and cage assemblies and components with the outer ring can be installed separately. Roller and raceway contact at the contact line can reduce the stress concentration. The tapered roller bearings can only pass one-way axial load, so as to pass the opposite direction of the axial load on the need install another with symmetrical tapered roller bearings.
TIMKEN tapered roller Cylindrical roller bearing features:
Tapered roller shall be so designed and outside roller and raceway contact line lengthening intersect at the same point on the bearing axis, in order to achieve pure rolling. Are separable bearings, the bearing inner and outer rings with tapered raceways are, for the frustum-shaped roller. Roller and raceway contact can withstand heavy radial and axial joint load, but also bear the pure axial load. Larger the contact angle, the higher the axial load capacity. Newly designed tapered roller bearings used to strengthen the structure, the roller diameter increased, the roller length longer, increasing the number of rollers, used with crown roller, so that the bearing capacity and fatigue life improved significantly. Roller end with the big wall between the use of the sphere and the cone contacts, improve lubrication.
